Abstract

The invention belongs to the technical field of adhesives and particularly relates to a method for preparing an edge sealing hot melt adhesive for furniture. The method comprises the following specific steps of: putting ethylene-ethylene vinyl acetate (EVA), a tackifying resin, waxes, a 4-[beta-(3,5-ditertiary butyl-4-hydroxy phenyl) propanoic acid] pentaerythritol ester, a filler and dibutyl phthalate into a mixing roll for mixing, heating to raise the temperature to be between 90 and 100 DEG C and mixing the components for 25 minutes; and adding a uniformly mixed product into a double-screw extruder and cooling and pelletizing the extruded product to obtain the edge sealing hot melt adhesive for the furniture. The product greatly lowers production cost and has higher adhesive strength.

Description

technical field [0001] The invention belongs to the technical field of adhesives, and in particular relates to an EVA-type hot-melt adhesive for furniture edge sealing and a preparation method thereof. technical background [0002] Hot melt adhesive has the reputation of green adhesive. It is solvent-free and pollution-free. It has fast curing speed, high production efficiency, convenient storage and transportation, and good adhesion to various materials. Its application fields are becoming more and more widely. In particular, the demand for ethylene-vinyl acetate copolymer EVA type hot melt adhesives is large and the wide application range accounts for about 80% of the total consumption of hot melt adhesives. Since the hot melt adhesive is solid at room temperature, it can be processed into film, rod, strip, block or granular according to the user's requirements; different materials can also be used to prepare different formulas to meet the softening point, viscosity, embr...
